To the top bar, d, of frame G is attached a IoO 5o A is the main frame of the loom. A is the stand, a, to which is pivoted the lower end of arch thereof 5 B, the crank-shaft; a, the beam rod m, which is pivoted at its upper end tothe inner arm of lever 7c, the latter being` pivoted upon bracket u, secured to the arch A', and having pivoted to its outer arm the upper end of rod g, which at its lower end is pivoted to the lever O. Slots are formed in the ends of the levers k and O and in the bracket u, to provide for adjustment of the pins connecting the rods m and g to the said levers and of the' pivotal pin ofthe lever 7c. Lever O carries a stud or roller, o', (see Fig. 9,) working in the groove i of a cam,B, mounted in the stand H, (see Figs. 15, 16, and 17,) placed at the side of the loom, as shown in Figs. land 2. The cam R has cast with it or attached thereto a ratchet-wheel, R', which is engaged by a pawl, r, pivoted at the free end of a lever. T, turning loosely upon the shaft or arbor of the cam, said pawl being held in engagement with said ratchetwvheel by a spring, r', connected at its opposite ends to the lever and the pawl, as shownin Fig. 7, and said lever being actuated bya rod, t, that is connected with one end thereof, the lever being slotted at t to permit of adjustment' of the connecting-pin. The rod t at its other endis connected with a crank-V pin, fr, on the crank-shaft. The cam R, through the intermediate devices described, raises and lowers the needle-holding frame, or holds the same stationary in either raised or lowered position, as required for the production of the desired pattern. lts contour will be varied according to the character of the pattern to be Woven. At the rear of the needleholding frame and mounted in guides D D, so that it may slide freely therein from side to-side of the loom, is a reed, F. This reed Fis given a lateral movement in either direction after each depression of the needleholding frame, so as to `shift the standing warps (thosewhich are not passed through the eyes of needles g', but which are crossed by the latter threads) from one side to the other of the points of the needles, the rod e being connected at one end to one end of the reed F, and at the other to the armfi at the forward end of the horizontal rock-shaft L, the arm p on the rear end of said rockshaft being connected by the link Z to the arm s, resting on the surface of the pattern-chain s. Said chain is provided with risers foracting upon the arm s and the corresponding arm sl,hereinafter referred to, and is actuated by means of the pawl s, carrier s, and rod 7L, the latter being connected with a crank, h2, upon the crank-shaft, as shown.

rlhe reed-operating devices,so far as already described, are substantially as shown, de-` scribed, and claimed by me in my application tiled February 21, 1887, Serial No. 228,363.

ln 'order to provide for the production of a greater variety of patterns than it is possible to produce with the devices of the said ap plieation, and for the production of entirely different effects, I apply to the reed F, either at thc ends thereof, as shown, or at other desired places in the length thereof, plates F', slotted vertically, as shown, for the passage Vthe length of the reed.

and' movement of the warp threads. plates are secured to the side bars of the reed F by screws f2f2, that pass through horizontal slots f'f in the said plates, so as to allow the latter to slide freely in the direction of Each plate F' is connected by a link, o', to the lower arm of a lever, o, pivoted upon the upper side bar of the reed F, said lever being acted upon to move the plate in one direction by a spring, ot. The levers v are connected so as to move together by a rod or rods, g5, and a rod, e', extends from one of said levers to the upper end of an arm, i, at the forward end of the sleeve L', fitted upon and moving freely around the rock-shaft L, as shown in Figs. 18, 19, 20, and 2l. An arm, p', at the rear end of sleeve L is connected by a rod, Z', to the end of arm s, hereinbefore described. By this means an independent movement upon the reed F may be communicated to theyplates F'. When reed F is 4held stationary, the plates F', which constitute auxiliary reed-sections, may thus be moved to produce lateral movement of the Warps passed through the spaces thereof, and to cross-weave longitudinal borders or stripes in the fabric being woven, while,when lateral movements are again imparted to the reed F for the production of portions of the pattern extending more generally across the Width of These the fabric, cross-borders,orheadings, the auxiliary reed sections or plates F will move jointly with the latter.

The reed is constructed in substantially the manner already indicated in describing the IOO manner of applying the needles to the needle holding frame, the dents n' being separated by separating-pieces f 3, as indicated in Fig.

'3; and in practice both the dents of the reed and the needlesin the needle-holdingframe will `be divided oft' into groups, as required by the pattern, by spacing-blocks, such as presented in my application, Serial No. 228,363. ff are thescrews for `holding the dents, Snc., of the reed vclamped tightly in position. lf desired, the reed-d'ents maybe formed with slotted ends, as shown in Figs. 26 and 27, and be strung upon supporting-bars with forked sep arating-pieces and spacing-blocks interposed.

Having described my invention, I claiml. The combination, with the needles and needle-holding frame, of levers 7c and o, rods intermediate said levers and frame, cam R, ratchet-wheel R', lever T, pawl r, rod T, and the crank-shaft, substantially as described.

2. The combination, with the reed F and mechanism for imparting lateral movement thereto, of auxiliary reedsections movable v'with lsaid reed F, and mechanism for` imparti termediate devices for imparting lateral movement to said reed F, of the auxiliaryreedd sections F', movable with said reed F, and devices, substantially such as described, inter- IIO 5. The needle g', having an open eye, m3, and a tongue, gi", forming an integral part of the needle-body, and having` its tongue and the material adjacent to the said eye curved iu opposite directions, substantially as described.

In testimony Whercofl affix my signature in presence of two Witnesses.
